在最後一個歡迎介面上新增一個CheckBox.
// 2.新增4個UIImageView for (int i = 0; i < NEW_FEATURE_NUMS; i++) { UIImageView *imageView = [[UIImageView alloc] init]; imageView.size = scrollView.size; imageView.y = 0; imageView.x = i * scrollW; NSString *imageName = [NSString stringWithFormat:@"new_feature_%d",i+1]; imageView.image = [UIImage imageNamed:imageName]; [scrollView addSubview:imageView]; // 如果是最後一張圖片,則新增進入按鈕 if (i == NEW_FEATURE_NUMS - 1) { [self setupEnterBtn:imageView]; } }
/** 新增分享checkbox及進入微博按鈕 */ - (void)setupEnterBtn:(UIImageView *)imageView { // 0.設定imageView可以互動 imageView.userInteractionEnabled = YES; // 1.新增shareBtn UIButton *shareBtn = [[UIButton alloc] init]; [shareBtn setImage:[UIImage imageNamed:@"checkbox_unchecked"] forState:UIControlStateNormal]; [shareBtn setImage:[UIImage imageNamed:@"checkbox_checked"] forState:UIControlStateSelected]; [shareBtn setTitle:@"分享到微博" forState:UIControlStateNormal]; [shareBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; shareBtn.titleLabel.font = [UIFont systemFontOfSize:14]; shareBtn.titleEdgeInsets = UIEdgeInsetsMake(0, 16, 0, 0); shareBtn.width = 200; shareBtn.height = 44; shareBtn.centerX = imageView.width * 0.5; shareBtn.centerY = imageView.height * 0.75; [shareBtn addTarget:self action:@selector(shareBtnClick:) forControlEvents:UIControlEventTouchUpInside]; [imageView addSubview:shareBtn]; // 2.新增進入微博按鈕 UIButton *enterBtn = [[UIButton alloc] init]; [enterBtn setBackgroundImage:[UIImage imageNamed:@"new_feature_button"] forState:UIControlStateNormal]; [enterBtn setBackgroundImage:[UIImage imageNamed:@"new_feature_button_highlighted"] forState:UIControlStateHighlighted]; enterBtn.size = enterBtn.currentBackgroundImage.size; enterBtn.centerX = shareBtn.centerX; enterBtn.centerY = imageView.height * 0.82; [imageView addSubview:enterBtn]; } - (void)shareBtnClick:(UIButton *)btn { btn.selected = !btn.isSelected; DJLog(@"fdfd"); }
最終效果：
